In the residential sector, flip-up beds can prove their worth in bedrooms of small families or multifunctional rooms in apartments.

[0004] While the aforementioned technologies enable the self-standing and tilting of the boxless bed frame, in actual use, if the bed frame relies solely on hinges and hydraulic pneumatic rods to achieve self-standing, the lack of necessary support structures means that if the hydraulic pneumatic rods fail prematurely, they can easily cause injury to the user, making the bed inconvenient to use. Therefore, a boxless hydraulic bed frame that can stand upright is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a boxless hydraulic bed frame that can stand upright. It aims to solve the problem that in the prior art, if the bed frame is supported by hinges and hydraulic pneumatic rods, the lack of necessary support structure makes it easy to cause injury to the user if the hydraulic pneumatic rods fail prematurely.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1-3This utility model provides an embodiment of a boxless hydraulic bed frame that can stand upright, comprising a bed frame 1. The bottom of the bed frame 1 is rotatably connected to a hinge 4, providing a pivot for the rotation of the bed frame 1 and a base 2. The bottom of the hinge 4 is rotatably connected to a base 2, providing a bottom support foundation for the bed frame 1. The outer wall of the hinge 4 is rotatably connected to a hydraulic-pneumatic rod 3, providing power support for lifting the bed frame 1. The top of the hydraulic-pneumatic rod 3 is rotatably connected to the bottom of the bed frame 1. The top of the base 2 is provided with a support assembly to enhance the stability of the bed frame 1 when it is upright. 6. The top of the base 2 is provided with an auxiliary lifting component 5 to assist the initial lifting of the bed frame 1. The top of the base 2 has a groove 7 for storing the support component 6. The support component 6 includes a pivot 61, which provides a fulcrum for the rotation of the telescopic rod 62. The outer wall of the pivot 61 is rotatably connected to a telescopic rod 62 that can be adjusted in length in conjunction with a hollow telescopic rod 63. The hollow telescopic rod 63 is slidably connected inside the telescopic rod 62. The hollow telescopic rod 63 has a slot 64 inside that provides installation space for a return spring 65 and a locking block 66. Inside slot 64, a locking block 66 is elastically connected via a return spring 65. A crossbar 67 for moving the locking block 66 is fixedly connected to the outer wall of slot 66. A slider 68 for sliding the crossbar 67 is fixedly connected to the top of the crossbar 67. One end of the return spring 65 is fixedly connected to the inside of slot 64, and the other end is fixedly connected to the rear wall of the locking block 66. The locking block 66 achieves relative fixation between the telescopic rod 62 and the hollow telescopic rod 63. The outer wall of the locking block 66 engages with the inside of the telescopic rod 62 and the hollow telescopic rod 63. The outer wall of the crossbar 67 is slidably connected to the inside of the hollow telescopic rod 63. When the bed frame 1 is raised, the hydraulic pneumatic rod 3 extends synchronously, providing continuous support with its hydraulic power, pushing the bed frame 1 to rotate further upward around the hinge 4 as the fulcrum. At the same time, the telescopic rod 62 rotates out of the groove 7 around the pivot 61, and then the hollow telescopic rod 63 slides out from the inside of the telescopic rod 62. When it slides to a certain position, the return spring 65 in the slot 64 pushes the locking block 66 to pop out, so that the locking block 66 simultaneously engages inside the telescopic rod 62 and the hollow telescopic rod 63 for limiting.

[0033] Reference Figures 2-4The outer wall of the pivot 61 is fixedly connected to the inside of the groove 7. The outer wall of the telescopic rod 62 is placed inside the groove 7. The groove 7 can accommodate unused telescopic rod 62. The starting assist assembly 5 includes a bolt 52. The outer wall of the bolt 52 is threadedly connected to the inside of the bed frame 1. The outer wall of the bolt 52 is threadedly connected to the inside of the base 2. The top of the base 2 has a groove 51 that provides a sliding path for the first retaining ring 53. The first retaining ring 53 is slidably connected inside the groove 51. The inner ring of the first retaining ring 53 is fixedly connected to a first fixing block 54 that provides a bottom connection point for the spring 57. The top of the first fixing block 54 is elastically connected to a second fixing block 55 through the spring 57. The outer wall of the second fixing block 55 is fixedly connected to a second retaining ring 56. One end of the spring 57 is fixedly connected to the top of the first fixing block 54. The other end is fixedly connected to the bottom of the second fixing block 55. The spring 57 can generate an elastic force between the first fixing block 54 and the second fixing block 55. A slide rail is provided on the bottom upright of the bed frame 1. The slide rail provides guidance for the sliding of the second retaining ring 56. The outer wall of the second retaining ring 56 is slidably connected to the inside of the slide rail. There are two sets of first retaining rings 53. The two sets of first retaining rings 53 are mirror-distributed along the central axis of the bed frame 1. When the bed frame 1 needs to be changed from a flat position to an upright position, the initial driving force is first provided by the start-up assist component 5. The bolt 52 is loosened, and the compressed spring 57 is converted into an assist, which helps the bed frame 1 to start to lift around the rotation axis of the hinge 4, reducing the external force required for the initial start. Then the bed frame 1 is lifted manually, and the first retaining ring 53 and the second retaining ring 56 slide inside the slide groove 51 and the slide rail.

[0034] Working principle: When in use, the bed frame 1 is raised, and the hydraulic pneumatic rod 3 extends synchronously, providing continuous support with its hydraulic power, pushing the bed frame 1 to rotate further upward around the hinge 4. At the same time, the telescopic rod 62 rotates out of the groove 7 around the pivot 61, and the hollow telescopic rod 63 slides out from inside the telescopic rod 62. When it slides to a certain position, the return spring 65 in the slot 64 pushes the locking block 66 to pop out, so that the locking block 66 simultaneously engages inside the telescopic rod 62 and the hollow telescopic rod 63 for limiting. When it is necessary to change the bed frame 1 from a flat position to an upright position, the initial driving force is first provided by the start-up assist component 5, the bolt 52 is loosened, and the compressed spring 57 is converted into an assist, assisting the bed frame 1 to start lifting around the pivot of the hinge 4, reducing the external force required for the initial start. Then, the bed frame 1 is manually lifted, and the first locking ring 53 and the second locking ring 56 slide inside the slide groove 51 and the slide rail.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
